www.dell.com | support.dell.com The Dell Force10 operating software (FTOS) supports three other variations of Spanning Tree (Table 19-1). Table 19-1. FTOS Supported Spanning Tree Protocols Dell Force10 Term Spanning Tree Protocol Rapid Spanning Tree Protocol Multiple Spanning Tree Protocol Per-VLAN Spanning Tree Plus IEEE Specification 802.1d 802.1w 802.1s Third Party Implementation Information • The FTOS MSTP implementation is based on IEEE 802.1Q-2003 and interoperates only with bridges that also use this standard implementation. • MSTP is compatible with STP and RSTP. • FTOS supports only one MSTP region. • When you enable MSTP, all ports in Layer 2 mode participate in MSTP. • On the MXL Switch, you can configure 64 MSTIs including the default instance 0 (CIST). Configure Multiple Spanning Tree Protocol Configuring Multiple Spanning Tree is a four-step process: 1. Configure interfaces for Layer 2. 2. Place the interfaces in VLANs. 3. Enable MSTP 4. Create MSTP instances and map VLANs to them.
